Be it known that 1, JOHN W. CARLsoN, a citizen of the United States,residing at Eialt Lake City, in the county of Salt Lake and State ofUtah, have invented certain new ano useful Improvements in /VaterMotors;and Ido declare the following tobe a full, clear, and exact descriptionof the invention, such as will enable others skilled to which the paddleblades will extend into the waterv to be controlled.

Another object of the invention is to pron, nssrsnon on'onn nrennro'nnnnnnr vide an improvedconstruction of float and.

to provide the. floats with rollers, whichmay engage the sides, of docksor pier-s the rollers holding the floats in spacedrelation to the docksand piers and preventing the water motor from having transverse movementin in the art to which it appertains to make they stream and certain ofthe rollers engagand use. the same.

This invention relates to an improved water motor of the runningfstreamoperated type and one object of the invention is to provide a watermotor having an improved frame construction for carrying a generator anda water actuated driving means for the generator the driving meansincluding endless carriers and paddle boards pivotally connected withthe carriers and limited in their swinging movement in one direction sothat they may be held in an extendedposition when engaged by the runningwater of the, stream or river.

Another object of the invention is to provide the frame with improvedmeans for re leasably holding the paddle boards against downwardmovement into the running water thus permitting the motor to be renderedinoperative when desired.

Another object of the invention is to provide improved'ineans forpivotally connecting the paddle boards with the endless carrier chainsand to provide improved track' means for engagement by pins carried bythe pivoted end portions of the paddle boards, the track engaging endportions of the pins being provided with rollersso that they may moveeasily along the tracks.

Another object of the invention is to provide the frame with improvedmeans for moving. strips which extend. longitudinally thereof into andout of position for engagement by pins extending from the free endportions or the paddle blades, the strips when extended to an operativeposition engaging the pins and preventing the paddle blades fromdropping downwardly into the running stream.

Another object of the invention is to provide a motor having the framevertically adjustable with respect to the floats whicn float in thewater thus permitting the extent ing abutment shoulders "formed uponthe; docks or piers to prevent the motor from, being. carrieddownstream.

. This. invention is illustrated in the accompanying drawings, wherein:

lhis improved motor is provided with floats 1 which carry a frameincluding standards 2 and 3, the standards 3 being extended upwardly toform corner posts for a support or housing provided with a platform 4and roof 5. A generator 6 will be mounted upon the platform 4 and adriving shaft 7 will be rotatably connected with the corner posts 3 atone end of the housing. This driving shaft 7 carries a large pulleywheel 8 about which passes a belt 9 so that rotary movement can betransmitted to the generator 6, pump or other device which may beoperated from the shaft 7, and the shaft '7 further carries a smallpulley 10 about which will pass a belt 11 s6 that rotary movement can betransmitted to the driving shaft as will Upper and lower tracks 12 and13 extend longitudinally of the frame and are secured to the standards 2and and are braced by braces 1 so that the tracks will be held in theproper position, Each of these tracks is formed of a paddle strip asshown in Fig. 2. The frame will be provided with suitable horizontalbraces extending transversely thereof as shown inlTig. but these havenot been specifically described since the detailed structure will. bechanged according to the size of motor built.

The frame is provided between the upper and lower tracks 12 and 13 withlongitudinally extending beams 15 which carry bearings adjacent theforward and rear ends of the frame so that shafts 16 which extendtransversely through the frame may be rotatably mounted. These shafts 16carry sprocket wheels 17 about which pass endless chains 18. The chains18 are formed of links as shown in Fig. l and each chain is provided atpoints throughout its length with specially constructed links 19 whichare flattenedto provide extensions 20 as shown in Figs. 9-and 10. Theseflattened portions 20 are provided with openings to receive the pivotpins 21 which are secured to the paddle boards 22 and in addition topassing through toe openings of the flattened portions 20 of these links19. also pass through the bearing arms 23 of hinged brackets 2 1-secured to the paddle boards and having the extensions of the linkspositioned betw en their hearing armsit will thus be seen that thepaddle boards 22 will be hingedly connected with the endless carrierchains and may have swinging movement into and out of an operativeposition. The pins 21 are extended beyond the sides of the paddle boardsand have their end portions fitting into the tracks and provided withrollers so that the pins can move easily through the tracks. In order tolimit swing ing movement of the paddle boards and brace them whenextending in an operative position from the lower flights of the chains18, there has been provided bracing chains 25 which are connected withthe free end portions of the paddle boards and at their inner ends aremounted upon the pins 21. One of the shafts 16 carries a pulley wheel 26about which passes the belt 11 so that when the motor is in operation,rotary movement can be transmitted to shaft 7 from the water actuateddriving means for this shaft 7.

ld hen this motor is in place, it is not dcsired to have the motorcontinually in op eration and in order to render the motor in o'ierative, there has been provided means for preventing the paddleboards of the lot-(er flights of the chains 18 from dropping do on intothe stream or river. Each of the paddle boards is provided with pins 27at its free end which extend transversely from the sides of the paddleboards but are short enough so that they will not engage the tracks 12and 13. A stub frame 28 carried by the main frame and is provided withside 28 which extend longitudinally of the frame beneath the lowertracks 18. These side bars 28 carry pins 29 which eX- tend through slotsformed diagonally in supporting strips 31 so that the supporting stripsmay be moved transversely of the side arms 28 into and out of positionfor engagement by the pins 27 of the paddle boards. When the supportingstrips 31 are in a retracted position beneath the side bars 28 thepaddle boards may swing downwardly to the operative position but whenthe supporting strips are moved outwardly to an opcrat' position. thepins 27 of the paddle boards will engage these strips and the paddleboards will be held. in a substantially horizontal position and thusprevented from moving down into the Water of the stream or river. inorder to operate the strips and move them into and out of an operativeposition. there has been provided s afts 32 and which are positionedvertically of the frame. Each of the shafts 232 and 33 has a hook-shapedlower end portion 34.- which terminates in an upturned prong or fingerfitting into an opening of the strip 31 with which the shaft is con-Therefore when the shaft rotates. tne strips will be movedlongitudinally and. due to the pins 29 which pass through the diagonalslots 30. the strips will be moved transversely of the side bars 28 andwill be till the shaft moved into orout; ofi'an operative positionaccording tothe direction in which the shafts rotate. AI triangularplate 35 is mounted upon each of theshafts 32-and 38 and cables-36 whichare crossed as shown in Figs. 5 and G are connected with the plate asshown in these figures.

32 which is extended upwardly as shown in Fig. 1 andterminates inan'actuatin'g handle 37 is rotated, the two strips-will be movedlongitudinally in the same direction and both-will be extended orretracted at the same time. In orderto permit of the strips beingsecured in an extended or retracted position, the shaft 32 has beenprovided with a socket plate or disk 38 which is rigid upon the shaft.and provided with pockets 39 to receive a lug 40 carried by a lockingarm 41. This locking arm 41 is pivotally mounted by means of a bearingbracket 42 and has its free end portion cut to provide fingers e whichwill extend upon opposite sides of the shaft 32 when the looking arm orbar 41 is swung downwardly to an operative position as shown in Figs. 7and 8. With the locking arm swung downwardly to the locking position andthe shackle of a securing-lock passed through openings in the fingersas, the locking arm will be secured in the locking position and sincethe lugs will fit into one of the pockets 39, the shaft 82 will be heldagainstrotation and the strips preventedafrom accidentally moving intoorout of an operativeposition.

Each of the floats l is hollow and is divided into compartments bybulk-heads or partitions45 to prevent the entire float from beingflooded in case a puncture should be formed in one portion of the float.This will further permit watertobe placed in the compartments throughthe necks 4:6 and thus;

provide ballast which. will sink the floats into the water of the streamor river the desired amount and will also permit of water being placedonly in certain of the compartments or to a greater extent in cer-' tainof the compartments so that the motor will be level in case the weightis not evenly distributed. Caps 47 are provided so that the necks 4x6can be closed and prevent water from passing into the compartments whennot desired. In the preferred form, the motor will be positioned betweendocks or piers, each of which will include a wall't8 provided withabutment shoulders 49 and 50 and the floats will be provided withrollers 51 for engaging the walls 48 and holding the floats in spacedrelation to the walls and other rollers 52 and 53 for engaging theabutment shoulders 49 and 50 and preventing the motor from havingmovement down stream. These floats have tapered forward end portionswhich carry eyes 54: so that cables may be'connected with these eyes andTherefore, when.

A pawl-591s carriedby the frame58 and engages ratchet wheel 60 carried byth'eshaft- 57 so that when theshaft is rotatedthrough the medium. of the turning handle it is-desired61 to vertically adjust the frame, the shaft may be held againstrotation in an opposite direction and thus the frame retained at theadjusted position. In order to guide vertical movement. of the standardsand re tain the teeth of the standards in; engagement with th pinion 56,there has been, pro vided a roller'62 as shown in" 13. There has alsobeen providedlocking means for retaining the standard in a verticallyadjusted position which consists of" a locking block 63*which'isslidablymounted in one of the cross strips 6% of the frame 58* and" providedwith an actuating shaft or handle 65 which is slidjably mounted in; anopening" formed in a second cross strip 66'offt-ho frame. Thlockingblock' 63 is provided] with teeth as shown so that when thelocking block is moved to v the. teeth of this block will engage the,teetl'i of the standard 3 and thus serve'to securely lock the standardin the vertically adjusted position and thus remove strain from the p w.1 1 Latches 67 are carried by the floats for engaging rack bars 68carried by the standaid 2 and assisting in retaining the frame in araised position; These latches 67 are .pivotally mounted by bearingbrackets 69 and each is provided with atreadle 'extencan be easilyswungto an inoperative position when it is desired to lower the frame.From an inspection of Fig. 4, it will be seen that the standard 2 fitsinto guides 71 which.
